DEVICE FOR REGULATING AND CONTROLLING THE SUPPLY OF GAS AND AIR TO FURNACES.

SPECIFICATION forming part of Letters Patent No. 717,640, dated January 6, 1903.

Application filed November 8, 1901. Serial No. 81,599. (No model.)

To aZZ whom it may concern.-

Be it known that I, DESIDERIUS TURK, a subject of the Emperor of Austria, residing at Riesa, Saxony, Germany, have invented certain new and useful Improvements in Devices for Regulating and Oontrollin g the Supply of Gas and Air to Furnaces; and I do hereby declare the following who a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a regulating and controlling device which forms an improvement over the known rotatable valves by means of which the gas is periodically supplied to gas-furnaces with variable flame direction.

The improvements consist in'the fact that the loss of gas and the direct suction of fresh air into the chimney, which are unavoidable during the rotation of the dome with the known gas-controlling devices, are avoided and that ingiving the choice of three gasorifices controlled by the device it is renderedpossible to arrange the said orifices in a circle. By obviating the loss of gas and the direct entrance of fresh air into the chimney the danger of explosion is also vreduced toa minimum.

The annexed drawings represent two forms of the new regulating and controlling device.

Figure 1 is a vertical longitudinal section, and Fig. 2 a horizontal section on the line A B of Fig. 1. Fig. 3 is a vertical section of a modified form of construction. horizontal section on the line C D of Fig. 3.

The reversing dome a. has the usual external form, and the lower edge is inclosed in a water or sand trough g in the usual manner. The gas to be burned or fresh air, as the case may be, is conveyed through a pipe 0 arranged in the'axis of rotation of the dome or hell a, wherein the arrangement differs from that hitherto used with rotatable domes. side the dome o, the valve 0 is arranged, by means of which the supply of gas or air can be cut off before the dome a is rotated. The movement of the valve-plate d isefieoted by suitable rods provided for the purpose in such I Fig. 4 1s a play between the end of the supply-pipeand the dome. In order to allow of the dome a being more than normally raised for the purpose of cleaning or'repair, the nozzle 0' of the pipe 0 is preferably connected with the latter in such manner that it can be telescopically pushed upward. 'By arranging the conduit for the gas to be burned and for the air in the axis of rotation of the reversing dome a another advantage is obtained, which is known in connection with non-rotatable reversing devices, but could not hitherto be obtained with rotatable devices. This advantage is that the number of orifices controlled by the dome a, which orifices must be arranged in a circle with rotatory domes, can be reduced to three. With this construction the rotary valve is considerably smaller than was hitherto the case, owing to the closer arrangementof the orifices of the cond nits. The valve is consequently lighter and considerably more easy to move.

In the annexed drawings the three orifices arranged in a circle are indicated by 0' 0 0 The conduit 0 leads to the chimney, 0' leads to one of the gas or air preliminary heaters, and 0 to the other heaters. One of the two orifices 0 0 must always be connected with that part of the interior of the dome a. into which the gas or the fresh air is introduced, the other orifice being in connection with the orifice o in order that the fire-gases can pass away. In the annexed drawings the reversing dome a is represented with the orifice 0 open to the entrance of gas and the orifice 0 connected with o to allow passage of the firegases.

For the purpose of properly conducting the gas to be burned and the air to support combustion,on the one hand,and the burned gases, on the other hand, the interior of the dome .is divided, as usual, into two completely separated chambers I and II. The manner in which this division is effected is, however, ontirely different from that hitherto adopted. Instead of the usual diametric transverse partition two walls I) are arranged at an angle of two hundred and forty degrees and not reaching to the roof of the dome a, but covered in. Gas or air can only pass through the chamber Lwhile the fire-gases,which with the dome in the position shown in the drawings move in the direction of the arrows shown in Figs. 1 and 2, can only pass through the chamber II. To prevent the loss of gas and the direct passage of fresh air into the chimney, the lower edges of the walls I) must also be packed. In the construction represented in Figs. 1 and 2 the said lower edges rest lightly upon radial arms of the trough g. In the construction shown in Figs. 8 and 4 they enter grooves h, with which the said radial arms are provided.

The movement of the reversing dome is effected in the same manner as hitherto, except that it is revolved one hundred and twenty degrees instead of ninety degrees.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. A device of the characterdescribed, comprising a rotatable dome, a plurality of furnace-openings arranged beneath the dome, vertical partitions dividing the interior of the dome intoa plurality ofcompartments, a fuelsupply, a communication through one of the compartments between one of the furnaceopenings and the fuel-s11 pply, and acommunication through the other compartment between one of the furnace-openings and the flue, whereby as the dome is rotated the furnace-openings are alternately and successively connected with the fuel-supply and the flue.

2. A device of the character described,comprising an open-bottomed rotatable dome, three openings arranged beneath and controlled by the dome, one opening communicating with the fine and the other openings communicating with the furnace proper, vertical partitions arranged within the lower part of the dome and extending from the walls thereof toward the center and meeting at an angle of approximately one hundred and twenty degrees thus dividing the interior ofthe dome into two compartments, a segmental horizontal plate resting upon the vertical partitions and shutting in the larger compartment,afuel-supply,acommunication through the smaller compartment between the fuel-supply and the furnace-opening and a communication by means of the larger compartment between the flue and one of the furnace-openings whereby when the dome is rotated the two furnace-openings are alternately and successively brought into communication with the fuel-supply and with the line.

3. Adevice of the character described, comprising a rotatable dome, a plurality of furnace-openings and a flue-opening arranged beneath the dome, vertical partitions within the lower part of the dome and extending from the walls thereof beneath the center and meeting at an angle of approximately one hundred and twenty degrees thus dividing the interior of the dome into two compartments, a horizontal plate resting upon the vertical partitions and shutting in the larger compartment, means for sealing the lower terminus of the dome, a fuel-supply communicating with the interior of the dome and concentrically thereof. I

4. Adevice of the character described, comprising a rotatable dome, two furnace-openings and a flue-opening arranged beneath the dome, vertical partitions in the lower part of the dome and dividing the same into two compartments, a segmental horizontal plate resting upon the partitions and shutting in one of the compartments, a fuel-supply, an opening communicating between the fuelsupply and the smaller compartment, a valve controlling the fuel-supplyopeningand means for sealing the lower terminus of the dome.

5. Adevice of the character described, comprising a rotatable dome, two furnace-openings and a flue-opening arranged beneath the dome and separated by intervening walls, vertical partitions within the lower part of the dome extending from the walls thereof toward the center and meeting at an angle of one hundred and twenty degrees thus dividing the interior of the dome into two compartments, one communicating with one of the openings and the other communicating with two of the openings, a segmental horizontal plate resting upon the Vertical partitions and shutting in the larger compartment, a fuel-opening arranged in the center of the dome and controlled by a suitable valve, a fuel-supply tube arranged in the axis of the dome, means for telescopically connecting the fuel-supply tube and the fuel-supply opening, and means for sealing the lower edge of the dome.

6. Adevice of the character described, comprisinga rotatable dome, three openings forming segments of a circle beneath the dome, two of the said openings communicating with the furnace and the other of said openings communicating with the flue, vertical partitions arranged within the lower part of the dome and extending from the walls thereof between the center and meeting at an angle of one hundred and twenty degrees thus dividing the interior of the dome verticallyinto two compartments of dissimilar size, a segmental horizontal plate disposed upon the top of the partition and shutting in the larger compartment whereby a communication is established between one of the furnace-openings and the flue-opening, a valved fuel-supply opening arranged concentrically in the top of the dome and communicating by means of the smaller-compartment with the other furnace-opening, and means for rotating the dome through an arc of one hundred and twenty degrees whereby the two furnaceopenings are brought alternately and successively into communication with the fuelsupply and with the flue.

In testimony whereof I affix my signature in presence of two witnesses.
